Craig R. See, Ruth D. Yanai, Melany C. Fisk, Matthew A. Vadeboncoeur, Braulio A. Quintero, and Timothy J. Fahey. 2015. Soil nitrogen affects phosphorus recycling foliar resorption and plant–soil feedbacks in a northern hardwood forest. Ecology 96:2488–2498. http://dx.doi.org/10.1890/15-0188.1
Appendix C. Resorption results by species.
Species-level results of mixed linear models showing the effects of soil and fresh foliar variables on nutrient resorption across plots (n = 18) while treating stand as a random effect. Marginal R² values indicate the strength of the correlation between the two variables, while the arrows indicate the direction (arrows pointing up indicate a positive correlation, pointing down negative). P values for the coefficient are listed in parentheses. Soil pit contents used in the analysis were estimates of total pit content (g/m²) from the Oa horizon to 30 cm depth in the mineral soil. Foliar chemistry and resorption efficiencies reflect the plot mean of all species weighted by contribution to plot litterfall mass.
